The proposal has the potential to impact the Township of Verona based on the changes in land cover and runoff that will discharge towards Verona and the Peckman River. The site plans, prepared by Anderson Consulting Services and revised through May 6, 2024 and the Drainage Report, prepared by Paul W. Anderson, PE revised through October 30, 2023, have been reviewed in the context of the potential impacts on Verona. The comments below are based on a review of the documents that have been submitted. It should be noted that these comments are focused on the portion of the site that drains towards the Peckman and Verona, however similar comments should be applied across the entire site. 1. The are two separate HUC-14’s that bisect the property. The first HUC-14 includes the Canoe Brook and its tributaries. The bulk of the proposed improvements are within this HUC-14 and drains towards the south away from the Township of Verona. 2. The second HUC-14 includes the easterly portion of the subject site that drains towards Peckman River. For the purposes of this report, we will consider this HUC- 14 watershed the Peckman River watershed. Peckman River originates in Eagle Rock Preserve before winding its way northerly through the Township of West Orange, through the Montclair Golf Club, before entering the Township of Verona through the Essex County Park, across Bloomfield Avenue before eventually exiting Verona Township at its northerly border with Cedar Grove. 3. The survey depicts a ridgeline along the easterly portion of the subject site, that divides runoff between the two HUC-14 areas referenced above. There is an existing 25’ wide utility easement that traverses the site in a north-south direction located easterly of the ridgeline. Aerial
